Goodwill ends at Tesco

Predictably, I suppose, the season of peace and goodwill ends when the sales start. For me, signs that normal incivility had returned came when the man next to me at the customer service counter decided to be boorish and unpleasant to the young female assistant serving him. She managed it well, with a slight reddening of the cheeks developing in response to a tirade that sprang, seemingly, from nowhere. But the most striking them was that none of her co-workers offered any assistance or solidarity after the moron had left. Are they so used to it - or is it company policy not to show weakness in the face of aggressive behaviour?
